GREASE-CUP.

Specification of Letters Patent.

Patented Mar. 24, 1914.

Application filed September 19, 1912. Serial No. 721,137.

T 0 all whom it may concern Be it known that I, WALTER D. BANES, a citizen of the United States, residing at Germanto-wn, in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Grease-Cup, of which the following is aspecification.

My invention relates to improvements in grease cups.

The object of the invent-ion is to provide convenient and simple means for locking the cap in its position of adjustment and also means for removing the residue of grease from the .cup upon removal of the cap after the same has been moved to the final position on the cup.

Referring to the drawings which illustrate merely by way of example, a preferred embodiment of my inventionFigure 1 is an elevation of a grease cup embodying my in vention. Fig. 2 is a vertical section. Fig. 3 is a perspective view of the spring. Fig. 4.

is a perspective view of the cup with the cap or lid removed. Fig. 5 is a sectional view of the cap containing the residue of grease which has been removed from the cup. Fig. 6 is a vertical section of the cup with cap removed. Fig. 7 is a plan View of a ring having projections adapted to engage with a spring. Fig. 8 is a vertical section with the ring in position.

Similar numerals refer to similar parts throughout the several views.

The grease cup 8 and the cap 9 are of the usual type, one telescoping with the other, with the following additional features The cap 9 is provided preferably with an annular channel 10. In this channel 10 is seated the circular part of spring 11. This spring 11 is provided with the downwardly extending detent portion 12 with the inclined extension at its lower end.

The cup 8 is provided at its upper inner margin with serrations or recesses and projections 13, which may be provided by casting or bending the same integral with the cup as shown in Fig. 4 or by inserting a ring 14 such as shown in Fig. 7, in the annular channel 15 of cap 8 as shown in Fig. 6 and Fig. 8. This annular member or ring 14, having the projections similar to those shown at 13 in Fig. 4;, is preferably resilient, so that it may be snapped into position in the annular channel 15 and securely held in place. Inthe same way the circular part of spring 11 when snapped into position in channel 10 of cap 9 will be securely held in such position.

As the cap 9 is gradually screwed down on cup 8 to force the grease therefrom as the same is required, the extension 12 will pass over the serrations 13 step by step from one recess to another thus holding the cup and cap in desired relative positions after each manual adjustment of same, and will prevent any disturbance of such adjustment by the jolts or jars incident thereto. Another purpose of the portion 12 and the inclined end thereof is to keep the grease stirred in the cup 8. As the cap 9 is screwed down on the cup the inclined end of spring 12 engages the inclined inner wall of the cup 8 and scrapes the grease therefrom, thus keep ing the grease agitated and preventing a tendency to clog.

hen the cap has been screwed all the way down upon the grease cup 8, which for convenience we will call the final position, it is then unscrewed for a new charge of grease. 'VVhen the cap 9 has reached said final position the extension 12 of the spring will be forced into the position indicated by the dot-ted lines in Fig. 5 due to its engagement with the inclined inner surface of the grease cup as above stated. In this position as the extension 12 is rotated with the cap, it cuts the residue of the pot grease, cleanly from the sides thereof and removes the same therefrom with the cap as indicated at 17 in Fig. 5, thus leaving the cup clean for a new charge of grease. The cone 17 of grease may be readily removed from the cap 9, if for any reason it should be desired to do so before recharging the cap.

What I claim is 1. A grease cup having a converging interior contour, a cooperating cap and a detent for maintaining the relative positions of adjustment of cup and cap, said detent conforming to the converging portion of the' cup and adapted to extend into the same.

2. A receptacle, a cap having threaded engagement therewith, a spring secured to the cap, said spring having a permanently inclined portion adapted to project into the receptacle and to scrape the sides thereof, the receptacle provided near its mouth with serrations for cooperating with the spring.

rated member seated in the cup channel and a cooperating resilient member having 3. A receptacle, a cap having threaded engagement therewith, a member secured to the cap and adapted to extend into the receptacle and to scrapeothe sides thereof and 5 to remove therefrom the residue of grease the final position.

in the receptacle when the cap has reached 4. A receptacle, a cap having threaded Y engagement therewith, a resilient member secured to the cap and'adapted to extend 5. A grease cup, a telescoping cap therefor, threaded means for adjusting the cap with respect to the'cup, automatic means for maintaining said adjustment, and for withs drawing the residue of grease from the cup upon the removal of the cap.

v6. The combination with a grease cup and cooperating cap, of a serrated member adapted to be sprung into position against Z the cup and a, cooperating resilient member adapted to be sprung into position against the cap. s a

7. The combination with a grease cup and cooperating cap, each provided With an interiorly disposed annular channel, of a sera substantially circular extension engaging Copies of this patent may be obtained for in the cap channel and an extension projecting into the cup.

8. The combination with a grease cup and cooperating cap, the walls of the cup converging toward the discharge, of a series of projections circumferentially arranged about the inner wall of the cup and a resilient member carried by the cap and projecting into the converging portion of the cup, said member conforming to the contour of said converging portion and adapted to engage the said projections.

9. In a grease receptacle, the combination with the cup and cooperating cap, of a detent and an interiorly disposed annular serrated ring member engaged thereby within the receptacle.

10. The combination with a grease cup provided with an interiorly disposed annular channel, a cooperating cap for said cup,

a detent secured to the cap, and a serrated member adapted to be sprung into said channel and engaged by the detent.

11. The combination with a grease cup and cooperating cap, of a removable detent and a removable serrated member adapted to be engaged thereby to maintain the cup and cap in their relative positions of adjustment, said detent and serrated member being interiorly disposed with. respect to cup and cap.
